>>18442915The value of something in competitive 6v6 (assuming we're talking about OU) is determined differently from what you're thinking of.
-It's not a 1v1 situation. You have 5 other pokemon and so does your enemy. Both of you can switch in and out.
-Determining what moves it carries depends on what your other team members can or can't handle. CharX for example can choose Roost over EQ depending on whether you have an answer to Heatran in your team
-Different pokemon have different roles. As long as they perform that role well, they're ranked high. If they can perform multiple roles well, then they're ranked even higher.
With that said, Charizard's treated and judged as a nuke. It goes in on something that it can take a hit from (a predicted EQ, bullet punches, mach punches, predicted scalds if it's already mega evolved, as a revenge kill against something slower, against steels etc) and force the opponent to a tough spot. Does his Rotom-W stay in or does he switch to something else?
If he doesn't have a Chansey/Blissey/Goodra/special wall, chances are high he's going to lose his current pokemon or something's going to get crippled switching in. And the question really is, how many pokemon can be a safe switch-in if you consider Char Y's options?
Even resisted, drought fire blast hit something specially bulky like Latias for 41-49% and that's not mentioning dragon pulse which 23% of Charizards carry (based on Feb statistics). Bulky waters and rock types have to fear solar beam (standard move). Heatran has to worry about Focus blast (15.742%) or EQ (25.578%). Standard Ttar even has to wait a turn to change the weather to sand or it'll get OHKOd by Focus Blast even with vest.
Most of all, what pushes Charizard to be used so much nowadays is that people don't know if you have an X or Y. Getting a free DD for CharX or your Landorus-T getting OHKOed by Y fire blast is disastrous and a momentum shifter. Not every team has Chansey or a healthy special wall.
